I know that you can't change the weights in a driver once the round has started. What if a weight comes loose during the round? Can you tighten it with the tool? I searched the USGA's site and found a section on adjustable weights, but couldn't find the answer to my question. The answer is probably in the decisions book.

Sure. Just as you may replace lead tape that has fallen off during a round. I can't see why not. ...but I didn't look at the decisions book/section either.

I figured it's ok, but I had a friend ask and I wasn't 100% sure.

It sounds logical....then again we're talking about the USGA.

This is a really good question, thank god my driver does not have any swing weights. Do you think this would fall under the category of a damaged club?

4-3/2 Meaning of “Repair”

Q. During a round, a player may repair a club damaged in the normal course of play, or he may have it repaired by someone else. What does the term “repair” mean within the context of Rule 4-3a(ii)?

A. The term “repair” in Rule 4-3a(ii) means to restore the club, as nearly as possible, to its condition prior to the incident which caused the damage.



4-2/0.5 Lead Tape Applied to Clubhead or Shaft During Round

Q. With regard to Decision 4-1/4, may a player remove, add or alter lead tape during a round?

A. No. However, lead tape that becomes detached from the club in the normal course of play may be placed back onto the club in the same location. If the lead tape will not remain on the club in the same location, new tape may be used. Every effort should be made to restore the club, as nearly as possible, to its previous condition. Alternatively, the club may be used in its damaged state (without the lead tape) for the remainder of the round (Rule 4-3a).

If the tape is altered or damaged other than in the normal course of play, the club may not be used for the remainder of the round, under penalty of disqualification (see Rules 4-2a and 4-3).



Sounds like you are entitled to have the club play as it was before the round started.
